Understanding binding collections

JavaFX 10 supports three main collection types—List, Map, and Set.

You can make any Java collection observable using FXCollections helper methods:

List observableList = FXCollections.observableArrayList(collection);

This makes a collection trigger a listener on every addition, removal, or change in the elements order.

The FXCollections class mimics java.util.Collections a lot, providing observable counterparts for java.util.Collections methods.

Note you can go even deeper, observing not only a collection but the collection elements' changes as well, using the following method:

<E> ObservableList<E> observableList(List<E> list, Callback<E, Observable[]> extractor)

Here, you need to additionally provide the  ...
